The ATC-X replaces the ATC-1 Tone Chameleon, the first synthesizer made by Studio Electronics and at the same time the first synth with exchangeable filters. It is monophonic and has a ring modulator, a distortion, noise as well as an external input for a large variety of sonic experiences. Of course you can save your sounds in the internal memory and like its big brothers it understands lots of MIDI-controllers.

VOICE ARCHITECTURE Two voltage controlled discrete analog oscillators Waveforms: triangle; sawtooth; variable width square. All waveforms output simultaneously. Osc 2 to syncs to Osc 1. Dedicated Mini and Quad discrete filter systems Streamlined internally mounted integrated filter board designs: Option #1: Mini filter. Option #2: Mini; S.E.M.; 303; 2600. Discrete analog Ring Modulator External carrier input for external signal processing (bypasses Oscillator 2 function). Discrete analog Distortion Circuit Per patch programmable level control. Three multiple stage envelope generators Attack; decay; sustain; release with inverting and multiple triggering. Envelope 1 fixed to filter frequency. Envelope 2 fixed to amplifier level. Envelope 3 is assignable. Oscillator 2 audio frequency modulation (cross-mod). Destinations: Osc 1 frequency; filter frequency. Two low frequency oscillators Waveforms: triangle; sawtooth; reverse sawtooth; square; noise; random. Parameters: destination; depth; key trigger; phase; midi sync. Additional features White noise generator. External input processor. Exponential glide. Parameters: time; autoglide interval; destination. MIDI specifications In and out. Receives: program change; bank select; glide on/off; glide time; volume; sysex. Controllers: dynamics; modwheel; bender; pressure (each with one destination and amount). Fixed continuous controller assignments for all key functions. Modulation destinations LFOs 1&2 and envelope 3: VCO 1&2 frequency; pulse width and mix level; VCF frequency and resonance; noise level; Xmod mod amount; LFOs 1&2 rate and depth; VCA level. MIDI controllers Modwheel and pressure: all LFO1&2 and envelope 3 destinations including envelopes 1&3 amount. Dynamics: envelopes 1,2&3 amount. Bender: pitch; filter frequency.
